Vulnerability details
The vulnerability allows a remote attacker with low privileges to write attacker-controlled bytes outside OpenClaw's intended voice staging directory.
The vulnerability exists due to double decoding of attachment filenames in QQBot voice forwarding, which restores encoded traversal segments after filename sanitization. A remote attacker with low privileges can supply a crafted QQ attachment that the agent forwards as voice to write to another process-writable location, although generated filename material limits targeted overwrites.
